Nigeria and Kenya have voiced their solidarity with the UK after yesterday’s deadly attack near the Houses of Parliament in London.

A lone attacker was shot dead after he used a car to run down pedestrians, killing three, and fatally stabbed a police officer outside Parliament.

In a statement, Nigeria’s President Muhammadu Buhai said Nigerians “stand with Britons at this sad and trying moment in their country”.

He added that the whole world should unite to defeat “terrorism”.

In a tweet, Kenya’s Foreign Minister Amina Mohamed said: “Our thoughts and prayers are with the victims, families and friends of the brutal terrorist attack in London.”

She added:

Seven people have been arrested and six addresses raided in London, Birmingham and elsewhere in the country in connection with the attack, police say.

A total of 29 people injured in the attack have been treated in hospital and seven remain in a critical condition.

Police Acting Deputy Commissioner and Head of Counter Terrorism Mark Rowley said:

The inquiries in Birmingham, London and other parts of the country are continuing. It is still our belief – which continues to be borne out by our investigation – that this attacker acted alone and was inspired by international terrorism.”
